BREEDERS SEMEN-PRESERVER.

Specification of Letters Patent.

Patented Feb. 4:, 1919.

Application filed June 8, 1917. Serial No. 173,585.

To all whom it may concern:

Be it known that we, ERICK P. BERGMAN and FRANK McMUnTRnY, citizens of the United States of America, and residents of Cherokee, in the county of Alfalfa and State of Oklahoma, have invented certain new and useful Improvements in Breeders Semen-Preservers, of which the following is a specification.

This invention relates to devices employed in the breeding of live stock and has for its object the provision of novel means for retaining semen at a predetermined temperature, the conditions'of which are well known to those skilled in the art.

An object of this invention is to produce novel means for maintaining practically uniform temperature of the aid semen and for providing novel means for controlling the temperature and for provldlng 'an easilytransportable container and heater, the said invention also comprising novel means whereby the temperature may be controlled as stated and whereby observations may be made as to the temperature and other conditions.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote correspond ing parts in the several views and in which Figure 1 illustrates a vertical sectional .view of the apparatus;

Fig. 2 illustrates a plan view with the cover removed; and

Fig. 3 illustrates a perspective view of the heat controlling medium.

In these drawings 5 denotes a fuel reservoir and is primarily adapted for containing kerosene oil. The reservoir has a cover with an opening 6 closed by a stopper 7 through which the magazine or reservoir may be filled. A lamp burner 8 has a wick 9 extending into the reservoir and the upper end of the wick which projects through the burner is partially embraced by controlling wings 10 and 11, each of which comprises flangw 12 at the ends and top, the top flanges and portions of the bodies being cut away to form recesses 13 so as to obviate a complete smothering of the flame after the wick is lighted. The wings or controlling members each have cars 14 which are mounted on a pivot 15 so that the said wings may swing laterally of the wick for incasing or unshielding the said wick to a greater or les degree depending upon the flame and the degree of heat required.

Each of the controlling wings has a laterally weighted extension 16 which normally swings the shield outwardly and the weighted extensions are engaged by arms 17 and 18 of a lever 19 which is oscillatingly mounted on a pivot 20 carried by the burner. The arms are intended to engage the weighted extensions and to move the controlling wings laterally according to the operation of the lever as it is controlled by the thermostat 21 which thermostat operates on an arm 22 slidable vertically of the casing or housing 23. The said arm 22 consists of a rod around which there is a coiled spring 24 at its upper end. The rod is guided in a pipe 22 and the spring has one end bearing against the said pipe and the other end bearing against a shoulder on the rod. The spring 24 and an adjusting screw 25 which is threaded in the cover 26 of the cup 27 permits the regulation of the thermostat so that it will operate at a predetermined temperature. A thermometer 28 is also carried by the cover 26 and is exposed outside of the cup so that it may be read through a glass plate 29 carried by the cover 80 which is hinged to the casing 23.

A receptacle 31 is applied to the interior of the casing and is spaced therefrom by insulation 32 such as asbestos and the said receptacle is supported in the casing in any appropriate manner to produce an intervening space between it and the lamp burner. A conduit forming diverging pipes 33 and 34 is mounted in the receptacle and the pipes extend through the receptacle and through the casing so that they may carry off the products of combustion from the lamp, it being shown in the drawing that the chimney 35 of the lamp extends into an opening 36 which communicates with the conduit so that the heat may circulate through the pipes which are surrounded by water in the receptacle so that the water will be heated and will retain the heat and will not be affected speedily by external influences. By this arrangement, provision is made against the sudden temperature changes and it is possible for the thermostat to operate to maintain the temperature practically uni form. A cup 37 extends into the receptacle and is practically surrounded by water and is intended to contain instruments which will be sterilized and kept at the proper temperature for use in administering the semen or in collecting the same.

Cups 27, 37, and 38 and 39 are also supported so that they depend or extend into the water of the receptacle and they likewise are maintained at approximately uniform temperature and they are intended to contain or hold the semen bags 40. The semen bags 40 are designed to hold the fluid and the bag is placed in the reservoir and can conform to the contour of the said reservoir, it being understood that there are two such reservoirs so that fluid from different animals may be preserved and there is another reservoir for the sterilized instruments.

The cups bear substantially the same relation to the water containing receptacle in that they are surrounded by the water in channels which are practically uniform so that they will all have substantially the same temperature.

An opening 41 is provided by which water may be delivered to the receptacle.

The reservoir 5 has a shoulder 5 on which the casing 23 is supported, and the said reservoir and casing are connected together and held in assembled relation by hooks 5 pivotally connected to the reservoir and adapted to engage members 5 on the outer surface of the casing. Any number of these devices may be supplied according to the requirements.

A cooler or water tank 52 extends into the casing at its bottom and it is adapted to contain water which is maintained at proper level therein by the reservoir 44 having an apertured cover 45 so that when water reaches a level below the cover, air enters the reservoir and water escapes therefrom.

The wick 9 is placed in a pipe 27 and it extends through the cooling tank 52 for the purpose of preventing its being heated unduly and to prevent the formation of gas and avoid explosion.

The wick 9 is of course placed in the pipe 27* and into the burner as in lamps now in common use and the chimney 11 of the burner extends into the lower end of the conduit, all of which will, it is thought, be apparent to those skilled in the art.

A drain cock 43 extends through the easing and receptacle for the purpose of drawing water from the said receptacle.

From an inspection of the drawing and from the foregoing description, the operation of the device will be apparent, it being understood that the flame controlling wings are actuated in one direction by the thermostat and in the opposite directionby the weighted extensions and whentlie thermostat operates under the influence of the increased or higher temperature, the wings or guards are moved toward the wick whereas when the thermostat contracts and pressure is removed from the lever, the weighted extensions gravitate and move the guards away from the wick.

The functions, purposes and construction of other parts of the apparatus have been given in connection with the description of the elements and'it is believed that further detailed description is unnecessary.

In a semen carrier, a casing, a receptacle adapted to contain water therein, means for heating the water, cups supported in the receptacle adapted for the reception of bags containing semen, one of said cups being adapted for the reception of instruments for sterilization, a temperature indicating device in one of the cups, the saidcupshaving'substantially the same relation to the -walland other portions of the water containing receptacle whereby the said cups will be uniformly heated, and a controlling fdevioe contained within said cup for regulating the temperature .for' maintaining the tempera ture in the several cups uniform.
